Drink one sip everytime any place is mentioned. This seems like an easy rule and it may make you think that you need to add more rules to keep it intresting but because they are along a journey that takes them many places they mention the names of these places early and often.

If you are going to watch all 3 movies in a row, I suggest adding shot-gunning a beer everytime that anyone places the ring on. This only happens a few times in the movie and it makes for a good break in the action of just sitting and watching.
